Specification of Letters Patent.

Application filed November 4, 1910. Serial No. 590,764.

To all'whom it may concern:

' Be it known that I, 'WJLLIAM FnIoKs, a

subject of the. German Emperor, residing at Bethl'hem,in*the' county. of Northampton and State of Pennsylvania, have invented ing is a specification;

' The object of the present invention is to provide simple and eflicient means for exactly regulating the supply of gas to the different points of combustion in cokeovens Ovens have been known in which each heating flue or each smaller group of heating flues is connected to a separate passage or channel formed by the oven brickwork, such channels leading separately to the front or back of the oven where their inlets'and' thereby the gas supplied to each heating flue or each smaller group of flues can be "regulated. A so constructed furnace, however, is very expensive and the.'gas channels are not easily accessible for cleaning, etc.

To carry my improvements into effect, I provide a body, separate and independent from the oven brickwork and forming a number of passages or channels leading from the front or back of the oven where they are supplied with'gas to different points of combustion in the oven wall. Suitable devices provided in said passages or in the .GOIIIIIIOII housing from which these passages Qstart and movable from the outside, allow easy and exact regulation of aforesaid passages. By this construction the cost of the furnace is considerably reduced, leakage of the gas channels is made impossible and the latter are easily accessible for cleaning, etc., as the whole body can readily be removed from the oven.

In the accompanying drawing Figure 1 represents a vertical section through one half of an oven wall,.sho wing the proposed body in place. The other half of the oven wall is identical with the one shown but reversed. Fig. 2 shows on a larger scale part of the proposedzbody; the method of regulating the passages here shown ilffermg from the one shown in Fig. 1. F g. 3 1s a section on the line AB in Fig. 2.

Referring to the drawing, '1 .indicatesthe;

heating flues of the I oven wall below which the proposed body 2 is arranged. The latter is preferably made of cast metal and as shown on the drawing forms a number of I passages 01'- channels leading from a common housing or cap 3at the end of the oven to different points-of combustion. The housing 3 is supplied with gas from the gas main 4. By means. of: plug screws 5 having ta- Patented Dec. 19, 1911.

pered ends projecting through said housing f and movable from the outside, the inlets of the passages or channels can be separately regulated. The housing 3 as shown in Fig. 1 or,-according to the 'diiferent construction shown in Fig.- 2'the cover to the latter can,

if necessary, easily be removed. Even the whole body may for cleaning or other purposes be removed from the oven. The ends of the passages connecting to the heating flues are provided with nozzle-stones 6. With the construction shown in Figs. 2 and '3 the gas passages can be regulated by means of turn plugs 7 provided with a hole and projecting transversely through said passages. outside.

2. In a' coke oven or gas furnace a cast metal body comprising a plurality of pas sages leading from a common housing at one end of the oven to different points of combustionfor supplying gas thereto, and means for separately regulating aforesaid passages.
